Re: Macbook touchpad cursor moving "in steps"

I was having the same issues but noticed that when I did a fresh install the issue wasn't there so, I selectively edited my xorg.conf to get what I feel is a smooth scroll and tap-drag speed etc. Here is my section:

This makes it so you use two fingers for right click and three fingers for middle click. It also adds the two finger scroll.
Now you could add the lines for Horizontal two finger scroll etc, but I find that one rather annoying so I don't do it.
Anyways, I hope that helps.

Re: Macbook touchpad cursor moving "in steps"

kosumi68,

Thanks for the help. Just after I ran "rmmod appletouch," the cursor froze. Running "modprobe appletouch" made the touchpad start working again. I guess that proves I'm actually using appletouch. I have never used GSynaptics. I guess I should give it a try.

You know what, I think undertakingyou is right. I tried using the simple configuration in xorg.conf and the touchpad is performing better now. The motion "in steps" can still be noticed, but at least I have more control now.

Re: Macbook touchpad cursor moving "in steps"

I am still wondering about this; if your mouse is a geyser-like device, and for some reason the mouse is claimed by usbhid (there are two devices claimed according to the output you provided), then this might still be a module initialization race: appletouch might not have set the right protocol mode of the device. Two things to try:

1. Report the output of these commands

Code:

uname -r
lsusb

Given the device codes, I can check if it is a geyser device and how the usbhid module handles the mouse interface of that device.

2. Change the initialization order usbhid<->appletouch

/etc/modprobe.d/blacklist:

Code:

blacklist usbhid

/etc/modules, after appletouch:

Code:

usbhid

Make sure you spell the module names correctly: failure to load usbhid will make your keyboard not working -> booting from rescue disk.
